Dreamcast VGA

From Wikipedia, the free encyclopedia
The Kuro, a recent VGA box made by enthusiasts in Turkey.

The Dreamcast VGA Box (also known generally as a DC VGA adapter or DC VGA cable) is an accessory for Sega's Dreamcast video game console that allows it to connect to a video display such as a computer monitor or an HDTV set through a VGA port. Because the Dreamcast hardware can produce a VGA-compatible video signal natively, this connection provides improved picture quality compared to standard composite video or S-Video connections, along with support for progressive scan video.

Sega released the original VGA Box as an official accessory in Japan on January 14, 1999, at an MSRP of ¥7000.[1] It was only available in the United States via Sega's online store, retailing between $30 and $50;[2][a] but many third-party versions were also produced and sold worldwide in various form factors.

Most games for the Dreamcast are VGA-compatible, while various workarounds exist to enable VGA output from many of the games that do not feature official support.

Functionality

[edit]
Most VGA boxes also have S-Video and composite video output.

VGA output from the Dreamcast consists of a 640×480 image contained within a 720x480 frame that is drawn in progressive scan (480p), suitable for computer monitors and VGA-enabled television sets of its era.[6][7] The Dreamcast was one of the first consoles to support 480p and high-definition television (HDTV) in general.[8][9]

The official VGA Box includes a VGA connector for video output and a headphone jack for stereo audio output, with both intended for use in a typical desktop computer setup; it also includes A/V connectors intended for use with television sets common in its era, with an S-Video connector and RCA connectors[10] for composite video and stereo audio.[11][12]

Most third-party versions are functionally identical to Sega's model,[13][14] but some designs like Performance's add features such as VGA passthrough.[12][15]

Compatibility

[edit]

Software

[edit]

Most Dreamcast games are compatible with the VGA Box so long as they display in 640×480; this applies to most 3D titles.[16][17] Games marked as incompatible typically present an error message upon boot;[11] such a designation was determined via a simple toggle switch in the game's code.[16] As such, VGA output from most incompatible games can be forced via having the VGA Box unplugged while booting a game,[18][19] temporarily switching the VGA Box into TV mode while booting a game,[13] or using a boot disc such as DC-X.[20] This loophole is not possible for games that only display in lower resolutions, with most sprite-based games rendered fully incompatible with VGA output as a result.[16][21] Though a handful of sprite-based games supported VGA, most notably ones from Capcom, at least some, if not all of their sprites were originally designed for lower-resolution displays and may resultingly appear less detailed when displayed through VGA due to poor image scaling.[16][22]

Hardware

[edit]

Dreamcast VGA boxes are compatible with all Dreamcast systems regardless of region since each unit is capable of producing a VGA signal.[23]
